है ना तो आप आने वाले कल से सबसे सशक्त व्यक्तित्व हैं !

एक बच्चे के ��भिभावक आए PTM( उनका बच्चा एक बड़े ब्रांड की कोचिंग में २ साल का ड्रॉप ले चुका था ) में कहने लगे सर जबसे आपके संस्थान में बच्चे को भेजना शुरू किया है यक़ीन मानिए मेरी बी॰पी॰ की दवा का डोज़ कम हो गया है !

सुबह 7:30 पर उठ कर ऑफ़िस पहुँचना ,
लेक्चर लेना , स्टडी मटीरीयल बनाना , question बैंक तैय्यार करना , सबसे बेस्ट टेस्ट questions बनाना , अनगिनत क्लास टेस्ट कराना , बेशुमार doubt sessions रखना !
एक जुनून सा रहता है , आज तक कभी थकान नहीं हुई

All the best मेरे प्यारे बच्चों !
आज आपका NEET का इम्तहान है ना
जानता हूँ थोड़ा परेशान हो !
धड़कने बढ़ी हुई होंगी !
नीद भी नहीं आयी होगी शायद !
मन में तमाम उथल पुथल होगी
तमाम शंकाओं और कई ग़ैर ज़बाब के सवालों के कश्मकश के बीच तुम्हारा शांत बने रहना बेहद अहम् है !
