Do you worry about what a course of action will feel like? Do you think back to how previous experiences felt and use that as a guide?
It seems an obvious thing to do, however, if you stop and really think about it, you can’t actually recall how things did feel. Let alone how they will.
We all “guess” at it, and this often puts us off doing a great many things. It’ll hurt/be embarrassing/tire me/bore me. However, when we live life in the here and now, we actually get to really direct how things feel. If what we’re doing feels negative, stop or reduce it. If it feels good, increase it or continue.
Your current lived experience is the only time you’re genuinely feeling. The rest is an invention we’ve taught ourselves.
Learn to trust yourself in the moment and you’ll find you can do a great deal more and feel far more in control of your life. You’ll be making real world choices based on your thoughts and feelings & in real time.
Spend some time mulling over the above statements, then experiment. I suspect you’ll find it’s pleasantly surprising to live in the now and spend much less time “in” the past or future. You’ll waste far less time on concerns that will never happen or aren’t quite as you remember them.
