Do not think of sukha alone constantly. For, by doing so, you will only be making your fate feeble and unsteady. Instead, if you reflect upon the superb neutral position shining within your own mind, that very process will make your fate strong and steady. You will then be able to assimilate sukha as well as duhkha effectively and remain unaffected in both.  Indeed such unaffectedness is what qualifies one for gaining liberation.
