By next week it would be the first month of June and students will now be back at school and new graduates are either trying to find a job or are getting adjusted to their new jobs. My only hope for those new grads is that they be able to do well in life because I know what it feels like when your plans don't come true and you have to build with what's left while feeling uncertain about the future. If you know what you want, go for it and don't let anyone tell you otherwise. What comes to that question, it reminds of the song "What Do You Want Out Of Life" by The Tubes.
When you're young, you have all these expectations that you want out of life. One of the things that you should expect is not everybody will agree with what you want and they dissuade you and even make fun of your plans. Just remember, it's your life and you have thought over a thousand time and still want to go through with it, then go for it. Just remember to learn what you have to learn and get the tools that you need to make it happen. It would happen by waving a magic want but by hard work.
Do what it takes to make it come true but if it doesn't happen be ready with a Plan B. Still, there's nothing more fulfilling by having your dreams come true. That said, it doesn't hurt to listen to suggestions and even constructive criticism. If it's to help you get closer to what you want, take it. The road to failure starts when you please others instead of yourself so know what you want in life so you will be happy.
