It may seem like a good idea, but are you prepared for the consequences? Consider the likely outcome and think about what you can do to minimise the possible downsides.
You possess the qualities and abilities that you need to be successful and to do well in life. Life isn't a competition where you get awarded a giant trophy at the end. It's an ongoing journey from one destination to another, without a clear end. And that is what makes it exciting and unique for all of us; we are all on our own unique path. What makes the difference is effort, persistence and a belief that you can always learn and can always do better. Without these key ingredients, you're trying to paddle upstream with only one oar.
You need to find ways to reduce stress and calm your mind. Stop putting it off, or you could end up making things worse.
