Have you ever been wondering why is it so easy for you to give advice to others, but when it comes to finding pathways after facing roadblocks you get stuck? This is something that is not happening only with you and you should not blame yourself. However, it is not something that you cannot work on and improve.
You are usually feeling that way because you are emotionally charged about those certain circumstances, because something didn’t go how you pretended and hence miss to figure out plausible alternatives that might come in hand. Steve Chandler in his book Time Warrior: How to defeat procrastination, people-pleasing, self-doubt, over-commitment, broken promises and chaos has a chapter where he recommends a solution for those kind of situations. He suggests writing down the problem and trying to see it as a project, because that way you will not have the same feelings and perceptions about it as in the beginning. When you consider it like a project and not like a problem that you are trying to finish, it will be easier for you to think about it more reasonably and you will figure out a lot more possible side roads that didn’t even had in mind when you were first being challenged with the problem.
In conclusion, remember that being nervous and emotionally touched is only an alternative that sometimes consequently ends up producing regrettable results.
