If we decide for something then there must be the same strength/size/amount of something that is against our decision. Remember the law of polarity: Every thing has two sides and both sides have the same size. What are against our decision that we call doubts. In addition doubts are fear driven. To ignore, suppress or avoid our doubts would make them stronger… What we suppress/avoid will grow.
We schedule a time for our doubts, a half or one hour during the day. We face all of our doubts, go deep in them… Or even better to make a worry/doubts list, – write them down, prioritize them (the worst doubt/case is at first). Then we find for every doubt/case a solution/answer…. And then the doubts are gone …
If we make it so, we win confidence and quality time for our life.
If we can’t decide, then we make the same process; write down a list; pro and contra for any decision…. It is better to decide, even the decision is wrong than to live in doubts. Because the doubts are killing our energy and motivation.
