I took two major life to alter decisions which were very unpopular at that time. Here are few things I learned from that experience.
1. You don’t take a right decision. You take a decision and then make it right.
2. Write it down. Our brains tend to have circular/non-linear thoughts process. Write down your feelings, goals, ambitions, dreams, pros, cons and every little thing that go around your decision. We human are very visually oriented animals. It is easy for us to analyze rationally when things are visible. In this regards, try to bring your thoughts on a paper.
3. It should be your decision. I can’t emphasize this point enough. You should be prepared to face whatever comes on your way with the decision. As Frank Zappa said — “If you end up with a boring miserable life because you listened to your mom, your dad, your teacher, your priest or some guy on the television telling you how to do your shit, then you deserve it.”
4. Be brave. If you are afraid of uncertainty ahead, you are just being human. This is the time you can be brave. If you differentiate danger from fear, you can embrace the present state and take some rational decisions.
5. Collect information and not advice. Millions of peoples out there with million free advise. Every advice is coupled with personality, past experiences, responsibility and n-number of other factors. You can’t possibly share all of those factors with anybody else in this world. So nobody’s advice is perfect for you.
5. Trust your guts and take a calculated risk. It is not going to be easy but it surely will be worth it.
6. No regret policy. Looking back, I can label my decisions as good, bad, right, wrong, stupid, courageous, etc (I can do it only in retrospect) but there is not a single decision I regret. That helps me make peace with the present.
Good luck. Hope this helps.
