There is this sense when you are “young” that your accomplishments need to be a list of things that seem impressive to others. A list of several items you did. This isn't actually right, so here is another suggestion.
What is actually difficult, and worthwhile, instead is to do ONE single thing for a very, very long time. It's much harder and much rarer and results in outlier outcomes much more often. If I had only worked on a startup for a year, I would've gotten nowhere, the same way that if you work out for a few weeks and stop, it achieves nothing. Everything good in life comes from perseverance, but at the beginning, you're just like impatient: "I need to be somebody", "why does it take so long", the list goes on. Secret: you don't have to be somebody. You need just to be happy, what you're doing and make a living from it.
Be open for input
All of this is because it's the nature of the minds and the body to give up once things are hard and the easy fruits are picked already. Its why grit is so valuable. It's why Jeff Bezos is the richest guy and not the dude or dudette who did 10 startups for that same period. Compounding efforts produce outlier results. Yes, you can change directions to learn the tools, methods and strategies from other persons to accelerate your personal development. It's legitimate.
I'm lucky that my monkey ambition brain is satisfied (for now). Now that I'm on the other side of it, I realize a ton of time was wasted. Focus is what gets you places. Being deeply good at a single thing, or good enough at two, maybe three things.
Choose one thing and spend 5 years or 10,000 hours on it. At the end of one year you won't have a ton of signal that it's working, but you develop yourself in the right direction.
If you quit just after one year, you only prove to yourself, that you were right. But year two would likely be easier. Your network is wider. More people see your thing and recognize it and the current quality - if you do things right and develop yourself. So on with year 3, 4, 5, etc. Now you're really somewhere and hopefully like, what you're doing right now. Most people (competition) have quit meanwhile. So, you're now way ahead in a much less crowded pack.
When you feel like quitting, the thing you should really get out of it is not "I quit" but instead "ah! Most people probably quit at this time. If I continue, good things will happen and it'll be less competition." But don't get me wrong, operational excellence is mandatory and if you try to hold your breath until you can compete with the humpback whales, you'll fail. Do your due diligence before you decide and commit for a relative long period of time.
When you focus on your body, mind and soul success should come one way or the other in life and business life. There are still factors out of your control. You can call it, what you want, if you're a rational and logical person. Be open for new input and bold decisions in order to seize opportunities that may only arise once in a lifetime.
