We all have weaknesses. Some more then others but we all have them.
We can avoid our weaknesses, we can try to work around others weaknesses but at some point we have to deal with weaknesses (ours and others) and the best way to deal with them is to figure out what causes the weakness, work around the cause and then make the outcome as positive as possible.
An example would be someone who has a fear of public speaking. If you can figure out what causes the fear, you can work to overcome that and then the public speaking goes much better.
Working with weaknesses is just as important as working with strengths and those who ignore them will struggle.
Have a great day!
