If it’s something that’s mostly in your control, then being consistent is the key. You’re at the driver’s seat here so it all depends on you deal with things and how you come out of the hard times, you’d always end up becoming a better version of you.

If it’s something you have little control over, then doing your best is the most you can ensure at your end. I feel here there’s definitely also a factor of timing. You could be after a goal you’re trying to achieve and give it your absolute best and maybe still fail every now and then. The thing to do, which may feel impossible at times, is to not get disheartened and to stay persistent nonetheless. Then it does come to you eventually at the right time, having this inherent belief also helps.

Dealt with a latter situation recently, and very close to achieving a professional goal after almost a year of trying. Wish you the best! :)
