The sound philosophy  refers to is the attitude of success you build through the right thoughts, ideas, and beliefs. When you take such an attitude, the other pieces of your success plan function at a much higher level. Your future is within reach when you have a firm foundation on which to build and maintain it. Taking responsibility for your attitude is the first step. Most people hand over the responsibility for their attitude in the following ways:

• They point to personal circumstances as the reason for their attitude.
• They point to other people’s actions (or inactions) as the reason for their attitude.
• They point to luck (or lack of it) as the reason for their attitude.
• They point to their own flaws or failures as the reason for their attitude.
• They point to the world at large as the reason for their attitude.

None of these are suitable excuses to have a poor attitude. Sure, things happen in life you can’t control,  “You must take personal responsibility. You cannot change the circumstances, the seasons, or the wind, but you can change yourself. That is something you have charge of.”
