Finding the job that you can be totally satisfied by is very difficult, and will probably take a long time. For most people, they need to treat every job they have before then as an opportunity to improve their personal presentation, so that when a great opportunity comes by they won’t be over looked because they aren’t capable or impressive. Being able to impress people when you need to is the most important ability for anybody who is determined to get what they want in life. This doesn’t mean that you should be abusive, or a ‘shark’. Showing that you are able to work well with other people is a basic skill required in almost every job. If you show that you can only sap the motivation of others, and just generally be a poor team player, then the likelihood that you will get what you want from life will depend entirely upon your ability to do your job. But most jobs require some level of interaction with people who need to see you as a team member, and not being able to work with them is a death sentence.
