Thank you for asking sriramapriya. Thank you HP for placing this question as a prompt. I ask now for forgiveness if wordy. In the process of writing a hub this question offers considerations in that regard. That said, sharing a tad is:
I am diagnosed with three disabilities - Bipolar Disorder, Diabetes, and Osteoarthritis, of which each are debilitating represented as incapacity to do such and such at various times
The significant other of this Life I now live also has a debilitating diagnosis of two or more - Fibromyalgia, Chronic Fatigue Syndrome, Depression and more
Family members with better than, same as, and not so good.
And, friends of consideration
Hopes & dreams or as dreams of Hope or Hope for Dreams.
I now have millions - plural is emphasized & the question is "how" would I spend that. Spend means as a noun, Spend "An amount of money paid for a particular purpose or over a particular period of time." with the allusion of the second definition being "Pay out (money) in buying or hiring goods or services."
The problem is "How" do you as in me spend my millions.
The problem has been defined, the challenge has been accepted with dedication of acceptance.
Next, is the solution: (Rough Draft)
Dispense "X" $'s for immediate care of 1st 3 levels of Maslow Hierarchy of needs for a Friend & me = 2 yrs from escrow.
Next, Discover with TLC a group of who's to be trustees of three trusts. Defining the who's would be a time of fun, fun, fun . . .one smile at a time. Many considerations would entail both perceptions - feelings and emotions & perspectives of knowledge & wisdom as both individuals & of entities.
One group(s) for a dream - organization with a long life expectancy, individuals & maybe friends and relatives, though all are friends within friendly relationships.
One for the significant other - more her than me, (Her & me are as one in the decision making process. In the case of a tie the third undisclosed partner has only to . . . ) an organization & individuals of trust and etc than of likeability with a lean toward her needs met first & of order with focus on self actualization.
One for me with pretty much the same conditions of above as with her. Not of difference, just different.
The %ages have been decided. Seeking worth of tomorrow as unpredictable, although has probable with possible.
Achieve that over a reasonable time period of expectation. Meetings in a vacation setting. Having fun, fun, fun . . . one smile at a time . . .
