A loving influence that wants the best for you most often wouldn't force of pressure you into doing anything that may make you uncomfortable by doing risky activity. Helpful influences like teachers try to bring out your drive to do positive and teach you how to tell what is good for you than just telling you to do or not to do something just because they say so.
If someone where to encourage you do do your homework on time, get a job, or eat healthy it still takes your drive to follow through and do it, positive influences bring out the positive in you.
On the other hand, bad influences may use fear and peer pressure to force you to do things. It could be drug use or even making you do something positive, but it could still have a negating behavioral influence on you. I encourage you to hone your critical thinking skills and use will always be able to tell what will be positive and negative for you. Everyone is different.
