Wisdom is the sharing of wise experiences and knowledge, but a lot of it is common sense. The difference is how we apply this common sense - we all have the ability to keep going even when we face challenges in our lives - basically it comes down to your attitude. We can have a positive attitude towards life, or a negative attitude. We can focus on the good or we can focus on the bad. Keeping a positive mental attitude is one of the keys to success.
The choice is always up to you!
