There will always be a time where you 2nd guess yourself. You’ll think you should have done the other thing instead. But hindsight is always 20/20 so why bother with it? LEARN from that mistake so as to not make it again, but at the same time remember mistakes can lead to new opportunities.
Recently I have been dealing with these thoughts. Dealing with self doubt. But I don’t want to be stuck. So I look at the positives, look at the possibilities and use my support system. With these things in place I am better suited to succeed NOW!
