Life's a deal pot, there's always a trade coming in. In essence, you are always in a marketplace. You could loose value anytime, you could become the most relevant anytime, you could be sold, bought or trashed anytime. If you desire to remain valuable every time, know what part of you needs to go and what part needs to stay, learn to reinvent yourself always and still remain the same product that caught the eyes of the market in the beginning all at once.
