Take action. Doesn't have to be big, in fact small is better - anything to get off the fence. Then you have some momentum to build on. Most people don't realize that not acting is in itself an action. You are choosing not to improve your situation, to stay right where you are. Some people worry that they will make the wrong decision, so they freeze. Better to make a wrong decision than no decision. If you make the wrong decision, you can course-correct and move on to the right decision. Life is risky, there is no way to be right 100% of the time. The key is to investigate to the best of your ability, then act, evaluate, correct, and repeat until you find yourself where you want to be. Good luck!
