Unfortunately the world has not been organized in a way that there is someone there to show your way. Only movies. You are your guide. Ask for better without sadness. You will make mistakes sometimes. You should not follow only single person as a guide. Choose partial guides you can trust / you take his/her words seriously / he/she has interesting, challenging ideas and always check what you learn with the real world scenerios, do not hesitate to change them when necessary.
