Experience

To be experienced is a good thing, it helps you develop and learn, and enables you to help others do the same. All life is experiences. A succession of them. Some good, some not so, but all helpful if you learn from them. Some will teach you how to do things, or how not to. Some will teach you about other people. A lot will teach you about yourself - what you like and what you don't, what you're good at and what you're not, what you understand and what goes straight over your head. A few may give you faith and others may test that faith, but with each passing one you will become more experienced.
