First of all it's an amazing movie full of thoughts and it remember us about our human principal the first thing i can extract is : if you still looking in everything and digging in every subject you gonna lose your mind and you gonna act like anyone else .. just folowing normal and toxic people who are torturing themselves and they want also cause pain to others. the second thing is Hope and imagination ... even you are doing hardwork and you don't have good result, dont generalize your deception ... frustration is real, necessary but it goes because you can turn an overwhelming circanstance upside down .. even you are struggling .. DO NOT impact negatively ... you can cry, you can keep trying, you can also fail again but DO NOT spread negatives waves ... Love, sacrifice, achievement, Respect of promises, make sense .. these terms are real and as much as you believe in it as much as you are close to your goal. If you could not do it, try to help others .. and stay optimistic
