Everything is still cautious.

Whether we succeed after doing what we can (within our power) is all arranged by God (man proposes, god disposes), so we have to pay attention to our actions (plans) day after day (before reaching the goal of success). Probably everything in the world has a chance of success as long as it is prepared, (so we will enrich ourselves) and broaden our knowledge, so that we can appreciate the vastness of everything in the world. Everything (the success factor) is prepared later, so you have a confident plan, a chance of success and confidence!
