Wealth and success are two very broad nominalisations. A nominalisation being a noun (a thing) that doesn't exist in its own right - you can't physically see it, feel it or touch it.
If I said Big Ben to you, both of us would picture exactly the same building and clockface. If I mentioned a football, our mental images would be similar. If I say wealth and success, you and I and anybody else are going to have hugely different ideas of what that is and what it might mean to us.
Think about what people say: she's loaded; he's rolling in it; they're minted.
What does any of that mean? I remember doing my A-levels and watching one of my friends out at work earning 'nearly' £200 a week (which I guess would be worth £300-£350 in today's money) and thinking he was loaded. Is a millionaire 'rolling in it'?
To understand what we would consider wealth and success to mean, we first need to establish who we are. We then have a clear idea of what wealth and success would mean to us.
If you look at your plan and still feel jealousy towards others or feel that somehow it seems greedy then you need to re-address your plan - you haven't been entirely honest with yourself about what you really want out of life. You need to readjust your attitudes towards what you want to achieve.
Wealth means so much more than money. A wealthy person with no family, no friends and no social life may well be unhappy. Health has a huge part to play; doing things to keep yourself fit make a tremendous difference to our wealth in so many ways. How you value your own wealth is entirely down to you.
Your success similarly is for you to decide upon. A professional footballer shooting wide of the post might not feel too successful. A two year old boy kicking a ball for the first time is very successful. If that two year old has that success recognised and builds upon it, he can try to acheive what he deems the next success to be. Ulimately through a multitude of small successes he could end up playing at the highest level.
Never underestimate your own successes even if they are small by what you might expect others to think. As long as they are true to who you are, and are building towards the end goal that you truly want, they are just great.
