Well,if your hope flags you need faith and a little stoicism: stoical toughness to tough through the bad times.
In the dark days of '15 and '16, what kept me going was the faith that cryptocurrency would be mainstreamed. At the time, when I was still on Bitcointalk, I said as much: the catalyst for the next bull market would be cryptocurrency hitting the mainstream.
As of now, it has; even if penetration is slight, it's hit that critical mass.
Marc Andreesen was right: Bitcoin in '16 was like "Internet" in 1994. There's a long way to go.
I follow Bix Weir and his discussions with Clif High. I concur, everything seems to be in play now.
It should be a fantastic ride :)
