Most people have a desire to get along with others, to please others, and to, in general, obey others, for a lot of reasons, some well thought out and some not really thought about at all. But, it is wise to remember, that you have been gifted with your own mind, by the very same Creator that has gifted all with free will, and that the greatest usage of that free will, is to utilize it in a manner that provides the greatest service to others, as well as to yourself, in which, the truly wise understand the value of, as Shakespeare told us, "…to thine own self be true."
While people get into trouble for all sorts of reasons, if one takes an honest look, at decisions and things that they have done that gave them the most trouble, a significant amount of that time, there is blame that lays not so much exclusively at their own door, but blame that rests somewhat with someone else, that deceived us, tricked us, used us, or took advantage of us, by suggesting or pressuring us into making a fateful decision that resulted in very negative consequences, and pretty much our fateful decision, started not with the word: "No", but rather with the verbal word "yes" or mere silent acquiescence to their demand or request, even though, many times, within our mind, it cried out to us, that the correct answer, was indeed, no.
We have friends, parents, bosses, teachers, and associates, that we deal with day by day, but these people, in authority or not, our peers or not, are not perfect within themselves, and while many are good people with good advice, there are many more that are just plain wrong in what that they do, in what they suggest, in what they ask or request or demand that we do. It is those times, we should utilize the free will given to us, to stand strong, and to not give in to what we either know to be wrong in the first place, or to the temptation to do something that we suspect is wrong, or to unthinkingly just do it, when we should actually think it through.
The decisions that you make, day by day, define you as a person, those decisions, badly influenced by others or not, are still ultimately your decisions, in which you will have to take the responsibility of such, so that, while it is true in order that to make progress one has to move, not every step is the correct step to take, for some steps are on the wrong path, or in the wrong direction, and further to the point, the goals and desires of one person may be diametrically opposed to the viewpoint of another person, for they are not you.
Therefore, have the courage and the strength to make a stand, and to thereby walk away from what appears to be wrong, or at least, give yourself time to properly consider it, or to even consult with people of respect, rather than hastily make a decision that you may well regret, sooner or later. The very best time to do the right thing is at the beginning, when the decision must be made, of which, in life, in general, learn of the power and usefulness of saying "no", for the dead go with the flow, but the living do not necessarily have to.
