I know it is cliche but if there is a dream or a goal that you have, you can achieve it. Many people feel that they can reach that goal because they don't have the money, or they are a certain age, or they just don't think it's possible for a variety of reasons. But that's not true. There have been story after story told about how people have gone from rags to riches because they were that hungry to reach their goals.
You can do whatever it is you want to do, that's just facts. If you don't have the money to open that new restaurant, there are resources where you can get grants, or you can borrow money to get started. If your credit is not that great to borrow money, there are other resources that will help you in getting that straight too. So just as we have an excuse for every reason not to do something, there is also a solution to every one of those roadblocks you may experience.
Don't give up. Don't ever give in. If there is something that you want in life, go after it. Even if you take baby steps to accomplish it, do so. There is a plan and a purpose for us on earth and if you have a passion and desire to do something you can achieve it with a positive attitude, planning, hard work and faith the size of a mustard seed.
