Set reasonable goals/Milestones that you know you can achieve with a steady plan. Also I'm not sure what you meant by "When bitcoin is gone" as in when it gets banned from your country? when the price crashes completely? When bitcoin runs out? I think it's safe to assume that bitcoin won't ever be "Worthless" even with all the altcoins, as for bitcoin running out, we're still have over a hundred years left. Finally If you're extremely worried about "your" bitcoin disappearing don't use the same password of your wallet on other websites. Print multiple copies of your private key and keep them secured.
