Procrastination. The act of postponing, delaying or putting off, especially habitually or intentionally.
It's something everybody is guilty of, admittedly, some (Gretel) more than others. I doubt it has any pros but if peradventure it does, the cons surely outweighs it.
I'll keep things brief and refer to myself. Whenever I desire to do something (usually productive) and I end up pushing it away or pushing it all the way to the deadline (if any) before I get started at all, I end up feeling like absolute shit, pardon my French.
But I'm sure I'm not the only one that feels that way. Feeling like absolute shit is not the best feeling in the world, so how do I stop feeling like, yeah you guessed it, absolute shit. I happened to have come across a way, by chance, which has proven to be effective.
First, choose a time you're willing to start that thing you want to do e.g practicing the guitar by 11:30am and set a reminder with an alarm clearing stating what you want to use that allocated time for.
Step two, isolate yourself from others before hand and put your device on DND, choose your least distracting thing to do with your phone or whatever takes up all your mental space. In my case I avoid Facebook, YouTube and Instagram and stay on Pinterest, YouTube Music or X.
Third, DON'T HIT SNOOZE! Or clear the notification when it comes. Instead, tell yourself you're only going to practice your guitar playing for ten minutes and pick up that guitar.
When you eventually start your practice, you'd notice your body getting conditioned to it and you wouldn't be so eager to get back to your phone or games or whatever consumes all your valuable time, and slowly, you'd get in the zone and easily over your 10 minute mark.
It's not magic and on some days it wouldn't work out, but your determination and effort is required. Goodluck love.
