You have a full time job and a family. How do you squeeze out time for yourself to learn investing?

At least 1/2 an hour each day. If not then 20 minutes. If not then 10 minutes. If not then at least a video about investing. You can't find the time for it, so you have to make time depending on your priorities.

It depends how "hungry" you are and how important you deem investing to be. If you feel that it is not so important and it is not urgent, then you may put if off. But if you have a strong desire to explore the concept of financial freedom, investing is a great way to reach that goal.

If you can't keep up with the big boys, I suggest just put money in robos and leave them to grow passively.

I feel you! However, I think this is more of a matter of sorting your priorities.

If you can put aside one hour everyday to learn something, be it reading or watch some learning videos, at the end of a month that would have been at least 30 hours. More often than not, what you have learnt is cumulative and you would be surprised at how far you have come when you look back one day.

It's never too late to start, and the pace is your choice.
