A lot of us have ideas for starting a product/service/business. Most of us also have lots of fears apprehensions about taking the plunge. So what's keeping you from pursuing what you think will be a life altering decision?
Some reasons I can think of
Others will think it's a stupid idea
I'm not smart enough to get this done
The idea takes too much money
Family is a priority
Need to learn more skills first
Need a business partner
I don't have domain expertise
I'm not sure I can put in the effort needed
90% of businesses fail. So why bother?
I really need to work on this idea on my own before launching
This is not the right time for my idea
I would've done it if I were in the 'valley'
I am not sure I have the right personality for starting
this should've been a poll but I can't create one with my measly reputation.
"You don't trust yourself"
All the reasons you see listed in this thread are rationalisations your mind comes up with to trick yourself. When you think of them logically, they are pretty trivial.
Through our upbringing, we are taught to listen to others. That our ideas and opinions must be suppressed because it could make others feel bad. After years of this brainwashing we start to believe it deep down. Watch children. They just say things and do things without thinking. They are acting naturally. They don't worry if something isn't going to work out. They just do it. "Excuse" doesn't exist in their vocabulary.
You used to be like this. And you can train yourself to be like this again.
If you're interested in trying to overcome these obstacles, I've put together a course relating to these topics as it relates to programming. It's available at https://www.programmingspiritually.com
