Obstacles are part of life
It’s important to have obstacles and challenges when you’re learning something new. Hockey and soccer wouldn’t be interesting games unless the players had challenges to overcome.
You’re going to fall down, maybe even scrape your knee when you’re learning a new sport. The same is true when learning something new, like trading stocks. You’ll fall down and have some failures before you’re able to be successful.
Obstacles will come your way. If you can recognize or foresee what struggles you might have in the future, you may be able to push further past those obstacles.
