Self help is often neglected area, personally I never spend much time in flipping through key books and resources which forced me on war footing during later part of life. Agree, a good number of self help books may be promotional heavy. But we know how to separate good from bad now.
I start with few, please add as required.
Rich Dad Poor Dad: Robert Kiyosaki
Elementary book but powerful, let you know difference between expenses and asset. Excellent pointers at personal financial planning and career plan.
Business Model You: Tim Clark/Osterwalder
Unlike the business compatriot this may not be that successful. But overall packaging into a diagram is excellent. It will help you put a map in few days for yourself.
One thing: Gary Keller
Brilliant book for changing habits. I have applied few, highly practical. For example I used the concept to, how to avoid watching stock prices continuously.
Barking up the wrong tree: Eric Barker
Included this as it sets you to contrarian philosophy. Helps in breaking unwanted beliefs.
yes plenty of choices there, I am looking out for missing ones which are good as well. This is one area I am pretty miserable. Please educate me.
