Successess is a public owned asset, it is not limited to you nor I.
It is pertinent to note that you shall receive double of the measure which you give out. If you exhibit cruelty and selfishness it will surely find its way back to you in hundred hold.
The more people you help to succeed the more successful you shall become. The more people you make happy the happier you become, the more people you help to discover their selves the more intune you are with your life goals.
You cannot sow corn and reap weeds, so also you cannot sow happiness in the life of others and reap sadness nor success in the lives of others and reap failure.
The golden rule is, give out what you want first and it shall gather a multitude of its kind and find its way back to you.
