Love and infatuation are not necessarily the same thing. Be aware of your true feelings.
Rise above the negative attitudes and actions of others at this time and, instead, strive to achieve your goals in spite of their pessimism. They may have given up and prefer to criticise the world, but that doesn't mean that you can't continue to pursue your goals and do well.
If you want the trust and loyalty of others, you need to be a great mentor and supporter who leads by example.
