I can't help comparing this set of advices to its 2000y old stoics counterparts (no offense being intended to OP).

1) Never put your family, friends, or significant other low on your priority list.

> stoic way: definitely a stoic's one, we're meant to love nature and mankind.

2) Life is not a dress rehearsal—this is probably it. Make it count.

> stoic way: there's no joy in pursuing anything, because you'll always want more, thus you can't have it all and will feel unfullfilled.

3) How to succeed: pick the right thing to do

> stoic way: "How to die at peace: achieve tranquility" ~ do not seek success nor something to do.

4) On work: [...] it’s hard to be totally happy/fulfilled in life if you don’t like what you do for your work.

> stoic way: a fullfilled life is a life where you let nothing harms your tranquility.

5) On money: Whether or not money can buy happiness, it can buy freedom, and that’s a big deal.

> stoic way: true freedom comes when you don't own nothing and owe nobody.

6) Talk to people more.

> stoic way: learn and teach, but do not expose your inner feelings, let them pass on you.

7) Don’t waste time.

> stoic way: to embrace fatalism is to achieve tranquility. Time is meant to be contemplated.

8) Don’t let yourself get pushed around.

> stoic way: yes, don't let other's aggressivity have an impact on your tranquility

9) Have clear goals for yourself

> stoic way: yes, definitely, but those goals should get you to tranquility

10) However, as valuable as planning is, if a great opportunity comes along you should take it.

> stoic way: only if that opportunity will let you achieve a more peaceful state of mind

11) Go out of your way to be around smart, interesting, ambitious people.

> stoic way: be around peaceful, calm, wise people.

12) Minimize your own cognitive load from distracting things that don’t really matter.

> stoic way: yes, if what really matters is one own tranquility

13) Keep your personal burn rate low.

> stoic way: yes, if by a low personal burn rate you mean a high tranquility level

14) Summers are the best.

> stoic way: there's not real winter on mediterranean coasts :)

15) Don’t worry so much.

> stoic way: yes, definitely, never forget that your life is meant to an end sooner or later, always be prepared for that moment, die in peace.

16) Ask for what you want.

> stoic way: you should get rid of the feeling that you want things, it's a infinite loop.

17) If you think you’re going to regret not doing something, you should probably do it.

> stoic way: to regret something is only a consequence of wanting something, consider not wanting something at first

18) Exercise. Eat well. Sleep. Get out into nature with some regularity.

> stoic way: Excercise because it reminds you of your limits. Eat only what's necessary because it makes you enjoy good meals when it occurs.

19) Go out of your way to help people. Few things in life are as satisfying.

> stoic way: learn to love people whatever they do, few things in life can have more impact on your peace of mind that letting others behaviors perturbs you.

20) Youth is a really great thing. Don’t waste it.

> stoic way: youth is meant to prepare you to be a fullfilled elder, and in that sens you should not waste it.

21) Tell your parents you love them more often.

> stoic way: you sould tell yourself repeatedly how much you'll be sad when you'll loose your parents, because that will let you seek and enjoy their company more often. That works for family and friends too, of course.

23) Learn voraciously.

> stoic way: learn, then teach

24) Do new things often.

> stoic way: do less, seek peace of mind, that's where lies the feeling of an accomplished life

25) Remember how intensely you loved your boyfriend/girlfriend when you were a teenager? Love him/her that intensely now.

> stoic way: see 21)

26) Don’t screw people and don’t burn bridges. Pick your battles carefully.

> stoic way: avoid battles, battles lead to anger, anger lead to a crippled life by destroying your tranquility

27) Forgive people.

> stoic way: you sould have nothing to forgive at first, because you should not let others have impact on your peace of mind. However if someone asks for forgiveness, then let it be.

28) Don’t chase status.

> stoic way: definitely a stoic advice, don't chase fame.

29) Most things are ok in moderation. Almost nothing is ok in extreme amounts.

> stoic way: things are ok in scarcity, that's when you enjoy it most when it occurs.

30) Existential angst is part of life. [...] Nothing is wrong with you for feeling this way; you are not alone.

> stoic way: true, we are not alone and we are all humans. But that is false to suggest that it's ok the suffer angst, we should not let us be angst-ridden.

31) Be grateful and keep problems in perspective. Don’t complain too much. Don’t hate other people’s success (but remember that some people will hate your success, and you have to learn to ignore it).

> stoic way: oh yes, "you have to learn to ignore it", that's is very stoicish :)

32) Be a doer, not a talker.

> stoic way: be a thinker

34) Think for a few seconds before you act. Think for a few minutes if you’re angry.

> stoic way: think, then do nothing

35) Don’t judge other people too quickly. You never know their whole story and why they did or didn’t do something. Be empathetic.

> stoic way: yes, be empathetic, but do not judge at all, because it gives you no more tranquility

36) The days are long but the decades are short.

> stoic way: your life is long, as long as you contemplate every single moment
