Is it normal to think that life is a ladder?
life is a ladder and at birth you start out at the bottom, not knowing anything but being essentially a sponge and it is your "job" to learn and grow and get higher up the ladder by acquiring more skills and knowledge so that you can go up this ladder of life. Sometimes, if you are not fast enough or if you make a mistake you can and will take a step back on the ladder, but hopefully you find another way to go up again and pursue it.....along the way you look up to the people ahead of you on the ladder, the people who have done more, know more, have a high skill set/knowledge base than you. They are your teachers/mentors/people you want to emulate you do everything to learn as much as you can from these people so that eventually you can and will surpass them and when you do, there will be more people to look up to and you just keep going and going and going until your life is over and the ladder no longer holds meaning and you jump off of it and onto a new ladder in a different life.
