I chose a difficult path that other children around me did not choose.
「周りの子が選ばないような難しい道を選んできました」= I chose a difficult path that other children around me did not choose.
「周りの子」= (other) children around (me)
「選ばない」= do not choose; did not choose
「難しい」= difficult
「道」= path; road; way
「困難な道を選んだ方が、成長に繋がるから」= Choosing difficult paths leads to growth.
「困難な」=「難しい」→ difficult
「成長」= growth
「繋がる」= leads to; connects to
以上です。
ご参考までに。
