Persistency is vital. Every knock down is simply a brief pause on the staircase during your ascendancy to the next floor. Learn from it and persist until you succeed. It's really easy to succeed as every knock down just makes you stronger and more determined to reach your goal. Even the best, well thought out, beautifully laid plan means nothing until its implementation.
Action is the key.
Sure it's really important to contemplate your next step before you take it with a well structured plan but it means nothing unless you enact upon it. Sure as anything no one else is going to realize your goals for you. Only you can do this. I mentioned that you should dig into as much positive energy that you can. It is also a great idea to get into publications that are akin to where your interests lie.
