Stop moaning because it didn’t happen today. Nothing happens in a day. Everything is the conclusion of a prior set of events. That lunch you had, was cooked by the chef outback, who used the pre-prepared food, which came from the farmers markets, the butcher earlier that day, that came from farms, that were grown (or bred) over the past 12 months, that was cultivated land, that was cleared from scrub. Heck food has come a long way to get to you!
It’s exactly the same on any journey, focus on the bigger picture, have fun along the way (ie enjoy the journey, if you’re not, quit and try another journey), you’ll get there and it’ll get better. Just keep making the small iterative changes, be proactive, you can probably get there faster than you think (even if it’s not overnight).
