Changing anyone's life drastically isn't ever easy, even if one is to do it themselves. There are just a lot of obstacles that stand in one's way to completely change their lives to do what they dream of doing. That's why we call it a dream, it's something we wish to do, but we know it's never easy. We have to work to make them come alive.
There are things I wish to do in life; many things actually. I want to act, I wish to open up a dance school, I want to release my own album, I also have the desire to create graphic designs that people will look up to. These are all possible achievements, but they aren't all exactly easy. Nothing is stopping me other than the challenges to get out there and have it expressed. Life's a challenge, and you have to make your way up there step by step.
Something I also keep in mind is, "Through failure comes success." We won't always achieve want we want to do right away in life. There's always going to be those wrong choices we make, but we end up learning from them. These are what makes are dreams more worth working for because of ambition, and they all lead to a change in life.
Have I ever done anything amazing in life before? I've gotten to travel to many places, meet new people, and experience new things. All of which are life changing and allows me to see what's outside the walls that keep me. I'm also sure that there will be many more amazing adventures in life that I'll come to face. All in time.
Anyway, because these questions really relate to more of a person's life rather than a discussion of how life can be changed, I'm going to move this to OVP.
