We would never reach our goals if nobody helped us. Someone pushes us up instead of pulling us down. This person might be our friend, our teacher, or someone who is highly respected in our society. Whoever they are, one thing is certain: this person is not just with us, but they are for us.
I emphasize "for us" because not everyone who is with us is genuinely supportive. Some are only with us because they can still use us. Often, such individuals are opportunists and manipulators.
