The Time Will Pass Anyway
Time is the most common objection people use to justify not doing things. For instance, we all can see the rise of blockchain and cryptocurrencies as a single application of this great invention; what would be your first objection is I asked: Why don't you start learning blockchain development?
You'd be too concerned that it's going to take a long time, my best guess is; at least 3 years.
But, the thing is; the time will pass anyway!
If you decide to learn and if you decide not to, the time will pass either way.
Our first concern is always that things take time, even though the passage of time is inevitable, nothing can stop it, yet we use that as an excuse?
This is your sign to start doing the thing you always wanted to, but was so afraid that it would take a lot of time, because again, the time will pass anyway.
Always remember that!
