It's sad that most of the people I meet today can only be described as 'careerists'. I hardly see any artists or people who really enjoy what they do. And you know what your environment can do to you: it can make you or break you. Having an unhappy person next to you is a cyclic and disturbing process. The negativity percolates to unimaginable proportions. Negativity is often more affecting than positivity. That is why it is so important to 'engineer' your surroundings with care.
