If you do more than what you are paid to do, you will eventually be paid more for what you do. Don't ask for a raise because you need more money. Ask for a raise because you are worth more money. Your life will be much richer than if you had taken the other job. Take the pillow test to assess you career satisfaction.
Life just is.
It is what we make of life that will bring it nearer to what we want it to be. You are the best investment you will ever have. The dividends received on this investment will pay you back for the rest of your life. Be proactive in planning for the future. To get things in the future, you have to pursue them today.
