Every time I see people doing crypto then complains that they have done everything but still does not work for them.
The reason behind why they wont succeed is because they are counting the hours they have done the work, while they are complaining others are hustling and doing things extra mile.
It’s good you used cryptocurrency investment (bitcoin) as an initial example since this is a community that talks about bitcoin itself. But this is beyond only bitcoin, if you don't have the patience and endurance to keep going even at your biggest loss, you'll never be able to reach the success and happiness that you desire to and watch others achieve.
Time is valuable, and every time you spend learning a new skill and failing, you've merely covered up more time it'll take you to be successful in that skill. Every error you make along the road is a lesson you've learned and will not repeat, making your task shorter in minutes or hours to complete when you try again. No matter what obstacles you face, never give up; it's not over until you quit.
