>One of the pieces of advice I did not heed from my Dad was to try and save/invest 30% of your salary. This one is hard to understand until you are in your 40s and realise you are probably going to continue to work well into your 50s. A single, healthy, 20 something SWE can easily save 60-70% and retire before age 40 if you really try. I’m right around 50% now. The key is getting over that mental hurdle to where you start enjoying saving more than spending. I feel infinitely more fulfilled seeing $1,000 in my bank account than anything an iPhone X could ever do for me.
