Whether a business person is willing to go through all an entrepreneur must go through is going to determine how often a start up capitalist is willing to take themselves to make their venture work. So liking yourself is of the utmost importance.
Remember that taking shortcuts, cheating, or otherwise competing in the most honorable ways possible, are whether you feel good about yourself or not. Take every chance and make the decision you know you'll feel good about making, in order to keep liking yourself, more and more each day, incrementally.
When an adventurous, heroic capitalist is embarking on an adventure of any sort, for profit and glory, one must always be their own best ally.
