The first step towards a goal is always the hardest. Insecurities tend to seep into our minds, doubting our own abilities at achieving the goal, fearing the failure of an unknown outcome.
You have to make the decision and don’t look back after. This doesn’t mean to act rashly and make decisions out of a whim. This means to have faith in the decisions that you made. If you succeed, it’d give you confidence to do greater things. If you don’t, find an alternative path till you do. For all you know that path might lead you to somewhere better than your main goal.
The takeaway here is to let yourself be in constant motion towards a goal daily.
You might not achieve it immediately, but you’re definitely at better position than you were the day before.
