Is it by the number of good people you have in your life? Is it by how loved you are? Is it by pursuing your dreams no matter how big or small? Is it by the amount of money you make? Is it by the level of education you have? IMO, success is defined by a mix of several things. I'm not afraid to say I think money plays a role, but to me it doesn't end there. I think it's important to take care of your health. Being fit, taking care of how you look, staying healthy, etc are all very important parts of being a successful human being. I also think it's important to be passionate about something. It can be a hobby, or your career, or something you plan on working on more in the future, but having a passion, whatever it may be, is important if you want to be successful and happy. I think it's important to have people in your life. Whether it's your family, or good friends, or even just people on a forum to talk to, it's important to be able to talk to someone who is willing to listen. I also think money plays a factor. And not so much in terms of excess, but really more in terms of staying debt free and having enough to enjoy good things now and later in life. Being able to afford nice clothes, nice vacations, a nice home, fancy restaurants, and being able to save some for the future is ideal. I think it's important to let yourself loose and have fun sometimes as well. It doesn't have to be extravagant. A simple drive in your city exploring a new coffee shoppe or restaurant can be a very fun and rewarding experience. If you're a single bachelor, searching for a hot babe to explore with can be great. I mean why not right?
