There’s only one person in this world you can truly change and that’s yourself. Even that takes a tremendous amount of time and conscious effort. The only way you can change is through the conscious desire to do so and with lots of work, trials and patience.
It may be tempting to try to change someone who doesn’t want to change, as if your sheer will and desire for them to improve will change them. Unfortunately, that doesn’t work.
You might even actively choose people with problems, thinking that you can “fix” them. These individuals may also be looking for “caretakers” to “save” them, but these relationships are rarely healthy.
Let go of this faulty expectation. Build your life around genuine, positive people, and avoid problematic people that bring you down.
