We know what to do, we know what we love to do. Still, we are not doing anything about it. Later, this is what makes us unhappy.
When you take action and do something, there will be some people who say negative things about you. They will question your ability. The fact is, they do not know you and they do not have the context.
Some random guys on the internet say I know who you are, but the thing is, they don't. So their negative comment is irrelevant.
They think you cannot do it. You just do it and see what happens after 5 years. We have alternatives. You can focus on what you are good at and keep doing.
