In fact, I think that high expectations or hopes will be a great motivation to achieve it, likewise in investing we must have a plan and high expectations to motivate ourselves to achieve it and regarding risks or anticipatory actions must indeed be done and that is included in investment science and is not combined with things that spur motivation.
Expectations or hopes must be comparable to the motivation to achieve success because too much hope but not doing anything also does not give anything. In investing we do not prioritize expectations but planning and maybe expectations are only a small part to motivate ourselves. Risk can be anticipated if someone has good knowledge in running an investment and it will not be able to be anticipated if someone does not know the investment properly.
Many people are trapped by the success of others as a trigger in running an investment and they never see the process so that running an investment does not have the right knowledge. In fact, it will cause them problems instead of getting profit.
