What bothers you and why?

Don’t know why it feels more than before , am I running out of time?
When you were a kid you hardly cared about time. You were engrossed in something or in some thoughts that you hardly felt anything passing. Time ran so slow that it felt like you have the power to dictate time.
Then you started growing and slowly it seemed that the time was running quickly and has almost surpassed you.
And Now, you are far behind it and slowly losing hope of ever going to catch up with it. Maybe there is a scientific theory behind this feeling but surely all our worries, all are disappointments have a great deal of time’ s involvement.
What I think I can do to tackle this feeling is to keep myself busy in one or the other thing. This will surely stop me from worrying about the past or future and keep me in the ‘Now’
It’s difficult to be consistent with this, but you have nothing else but this to save yourself .
