Thank you so much @deanliu ! I very much appreciate your time and kind support :))

I actually think outside of investing, trading is also something everyone should know how to do on a minimum basis, and engage with. It takes a lot of time, effort, blood and tears to become successful no doubt, but it is a very worthwhile sport.
You don't have to day-trade and be in front of the screens 24/7. But consider having a small amount of capital ready and armed, sitting on a trading platform, for speculative trades when opportunities arise. This could be a leveraged dip buy during a correction in cryptocurrencies (I just made a new post with such a trade on ETH/USD if you wanna check out), trading Forex on leverage when big events happen (Brexit for instance, a good amount of traders at the prop trading company I worked last summer made $250,000 that night, or other geopolitical-economic events, such as elections), or perhaps stocks over big events like a CEO departing.

It really all comes down to discipline, patience, risk management, favorable risk:reward and a constant approach (that is iterated upon). Psychology is also huge. Again I highly recommend you consider looking further into trading if you find the time :)
If you do start, check out Elliot Wave Theory, Fib retracements and using Ichimoku clouds for technical analysis, and for Forex fundamentals there are myriads of resources online. I can forward you specifics if you would like!

Thanks again for your help fam :)
