Are you?
Does going university prepare you for the future?
Does taking after classes in what-not prepare you for the future?
To be ready is to be confident in yourself. Can you ever be confident enough to tackle the future?
Should we 'not think and just do'?
No ones ever ready for the future, you can only prepare yourself for whats to come. You don't know what the future holds, you only know what you are capable of. Use your strengths. Be brave.
