Bất kỳ một quan điểm nào cũng có thể thay đổi, điều quan trọng là bạn có “muốn” thay đổi hay không mà thôi. Mọi thứ không bỗng dưng mà có, thái độ cũng vậy. Để có một thái độ sống đúng đắn, trước tiên ta cần hình thành nó, rồi dần dần phát triển lên, biến nó thành tài sản quí giá cho bản thân. Một số người từ chối việc thay đổi, họ cho rằng “Tôi đã quen sống như này từ nhỏ, thay đổi chỉ làm cuộc sống thêm rắc rối mà thôi!” hoặc “Cha mẹ sinh mình ra thế nào thì cứ thế ấy, thay đổi làm gì cho mệt!”. Bạn cần biết rằng, không bao giờ là quá trễ cho một sự thay đổi. Nhờ thay đổi, con người mới có những bước tiến vượt bậc. Không chấp nhận thay đổi, cuộc sống của bạn sẽ trở nên nghèo nàn, thậm chí bạn sẽ gặp những rắc rối lớn. Bạn gọi một cái cây không đâm chồi nẩy lộc, không ra hoa kết trái là gì? Đó chẳng phải là “cây chết” hay sao? Con người chúng ta cũng vậy. Cuộc sống sẽ luôn được vận hành tốt nếu ta không ngừng hoàn thiện bản thân. Những ai không chịu thay đổi cho phù hợp với cuộc đời sẽ chẳng thể nào thích nghi được với hoàn cảnh. Có thể họ vẫn hiện hữu nhưng trong cuộc sống của họ sẽ bị tách biệt, không bắt nhịp được với đồng loại của mình. Đặt nhan đề cho đoạn trích
