Don't loss your optimism, there are some corrections but it's not a hardships, bitcoin has increased so far this year with a good rate and for it to start a bull run, it does not need 5 months or more to make it, at least that's what I know based on the past movement.
Yes, you are right based on the past experience it is very good to be positive in the market because if you compare Bitcoin price in 2018, now Bitcoin price increased more than 3 times, so due to some corrections we are facing some tactic situation in the market.
