It's About Your Mindset
Success is 80% mental processes and 20% procedures. Your strategy doesn't matter without the right mindset to implement it. Most people are held back by their own limiting beliefs -- they are the stranglehold to success.
Happiness is, without a doubt the most important thing in our life. If we are happy with ourselves, happy with our health, happy with our relationships, happy with our career our finances, there is not much else we need.
