1年前の僕は、副業にチャレンジしてみたいのに仕事に家事にやることが多すぎて時間が足りない、という悩みを抱えていました。そんな時に出会ったのがタイムボクシング。 ざっくり言えば仕事、娯楽、家事など1日のToDoを全て洗い出し、それをカレンダーに落とこむだけのシンプルなテクニックなので、最初は予定に縛られて自由がなくなりそうで嫌だな、と思っていたのですが、この後なにしようか、と迷ってる時間が無くなったことで驚くほど集中でき、実践してから1週間で生産性が上がったことを実感できました。 実際、私は本業をしながらタイムボクシングで仕事と家事を効率化し、余った時間の副業でこのアプリ作っています。 もしあなたが「余裕がない!」「時間が欲しい!」と感じているであればこのアプリをインストールしてみてください。必ずお役に立てるはずです。 (追伸) 自由時間を増やすコツはキツキツに予定を詰めすぎないことです。詰めすぎると時間に追われる感覚になり疲れてしまうので、重要度が低いタスクをしなくてもよくなる工夫をすることです!このアプリの今週のToDoという機能でやるべきことの優先順位付けが簡単にできるのでぜひ使ってみてください!
