You're going to have them no matter what you do!
If you are sick, you will have them. If you are well, you'll still have 'em.
Happy? You'll have them. Failing? Yep. You'll have them for sure.
What are they?
Get used to the fact that you will always have problems. Here's the real question:
Are you dealing with the right problems?
Are you experiencing the problems (challenges) connected to living your life of purpose?
Are you dealing with your own problems or somebody else's?
Are you focused on real problems or "fake" ones that you made up just to look busy?
You are going to have problems. Choose the ones attached to the life you want to lead.
