i know you've heard this but its important to remember this is a personal journey and comparing to the success of others will only cause you to feel like you're pace is slow ( i say slow because we don't generally compare with lesser accomplishments ). its your individual path and you should only compare your progress in terms of personal accomplishments. for me i am excited each time i learn something new because i was a person who learned most things quickly so though this has challenged me it has also humbled me and made me grow in ways i needed to grow. so keep pushing and learning and just don't quit.
